One soldier of the NATO-led International Security Assistance Force (ISAF) was shot dead by a man in Afghan military uniform on Sunday, in an attack that seems to be the latest in the so-called "green-on-blue" insider attack when Afghan army, police or gunmen in their uniform turned their weapons against their foreign partners.
